Model Number
This is the sensor
’
s model number (Factory Programmed).
FPGA
This is the FPGA version of the sensors.It is factory programmed and cannot be
changed.
Baud Rate
This is the sensor
’
s Baud Rate that it uses to communicate to the Host. To
change Baud rate select the Baud Rate from the list and click on
“
Baud
”
button. The available rates are 9600, 19200, 38400 and 57600.
Set Sensor Mode
The sensor mode refers to the format of the measurements(Imperial or Metric),
range and its accuracy. The sensor will
‘
see
’
targets only within its range
defined by
‘
MODE
’
. Note that all other parameters concerning range will be
interpret having the same unit as defined by
‘
MODE
’
. To change the mode,
select the desired mode from the drop list and click on
“
Set Sensor Mode
”
button.
Cosine Offset
‘
Cosine
’
is the cosine of the mounting angle of the sensor. To change the
cosine of the mounting angle, enter the new value in the edit box and click on
the
“
Set Offsets
”
button. This value is always set to 1.0000 if the sensor is
mounted perpendicular to the surface being measured. If the surface is more
reflective, better results are achieved if the sensor is mounted 20
from
perpendicular. Any angle can be used, but 20
is recommended. To
compensate for ranging at an angle, the cosine of the mounting angle must be
entered here. It is always a number less than 1. For example, the cosine of 20
is 0.9397. Incorrect settings may cause sensor to give false readings, or no
readings.
Range offset
This item sets an offset value which is added to the sensor range result, to
change its relative position. To change this value, enter the new value in the
edit box and click on the
“
Set Offsets
”
button. This value is metric or inches,
depending on the mode. This setting is very useful when mounting requires an
adjusted zero point.
